I io un ymiam filtymay concern:

` Be it known that l, Bronzini) E-lriivns'rnni of the town of Lindsay,in the coilny ol Victoriaancl Province of Ontario., Canada, haveinvented certain new and useful lnil proveniente in Traction-llruclis;and l hereby declare that the following is a full, clear, anclexa cirdescripiion of The saine.

This invention relates io certain new and useful improvements inagricultural inachines, having a traction truck io which can bedetachably connected `the separator of a threshing machine, or which canbe e1nployed'io draw a gang of blows, craig; a series of ciiltivators orseeding machines,

carry a harvester binder, or perform any other power Work ordinarilyinquired 'in fai'niinff o ereions.x the traction truck 'ticino' o D u nt.; provided with a' motive mechanism which caribe employed to propelAhe traction truck and aetnate the operating parte of the inachinepropelled thereby. l

The invention further relates to the neculw iai" constriiciion anniaifiangcincnt oi the main and 'fore carriages omisiituiing thecsseii'tial parte oi the traction trunk, and i'o the peculiar manner inwhich the sieering wheels lare connected to the fore carriage to comnpensatefor any variation in the level ol" the path over Which thc t'action truck is 'travelv ing, and to' the controlling mechanisn'i forthe steering Wheels Wl'iereby they will be uickl'y sensitive to anydcsirccl chungo or' (irection.

The invention 'further relatos to the wzil'ci rcooling means for theniotoi, which consists ofa fan carried by the traction liiick :unlforming an inseparable part of the motor employed to lpropel thetraction lrnck and actuante the driven parte of the apparatus and aWater casing also czliiicfl by flic trac- 'tion truck inclosing orpartially iiiclosing the fan casing, and suitably connecicd will: the.Water space of the wziei' jacln-b of the motor whereby a circulation olwam-r may beinailitained 'from izhc wzaicr jacket io thc water casingfrom which the heat uniis or calories are extracted by the circiilaiionof ihe air caused during the revolution of iilic fan.

Lilie chai-aciers of reference refer to like paris lhiolighoub thespecification and drawings.

The traction irich may bc described as consisting oi, a inairi carriageci supporied from the l'i'ziclion wheels c by the main cari'iagc ailleI), and a lorc carriage (l rigidly secured lo the liront cnil of theinain can ringej and supporlcd from the steering Wheels o by thel :lorccarriage axle and a (lolililc swiwlcd brochet, c.

The 'main carriage z is provided with two siffle beams y loczilcd .belowthe plane of the ainis of the inain carriage axle to carry the motor fi,anifl thc motor mechanism l1, below lhc plane oi' thc longitudinal axisof the main carriage axle o, so that the Weight oi the tracl'ion (truckand iis motor mechanism will be below the conter of gravity of theapparnllls lo assist, in counierbalancingille neighbor thc load carriedby the tract-ion Yii'nck.

By this means it is possibleto readily control the direction oi the movement of the traction truckunder favorable and unfavorable conditions, and to maintain theequilibrium oi the parts of the traction truck and the apparatus carriedthereby and thus minimize its vibrating and twisting movementsoriginating from the unevenness 'ot tl e surface on which the wheels aretraveling.

Connected to the arms of the fore carriage axle on the outer side of thesteering wheels 0 are the side balas j) of the steering frame. Thesteering tri/zine embraces the steering wheels preferably above theplane ofthe axle with suli'cient clearance between itself and thesteering wheels to allow or the tree revolution of the latter. Connectedto the side bars of the steering` trame in front of the arms of theI'ore carriage. axle f are steering chains Y adapted to be wound on the`Winding drums s actuated by the worm shaft 1. The worin shattz" isjournaled in bearings connected to the side beams g orn the maincarriage, and is actuated by the worm gear u driven by the steering masto. The revolution of the steering mast in either direction aetuates theWorm shaft or' the winding drums, to simultaneously wind one of thesteering chains and unwind the other when controlling the direction ofthe steering wheels and thus cause a quick responsive action of the:tore carriage axle, owing to the leverage exerted by the steeringchains resulting' from their attachment to the steering frame at thesides of the steering wheels in front of the forecarriage axle. Thisconstruction of the steeriirg` mechair ism renders the steering Wheelsextremely sensitive to any desired ehaiige of direction and renders itpossible to readily control `lthe direction of the traction truck underfavorable and unfavorable conditions.

The traction truck is employed to carry and support the separatingmechanism of a threshing outfit which may be described as consisting ofa separator i' detachably supported at its front end on the rear end "ofthe 'fore carriage platform /c and at its rear end on the side beams yof the main carriage, with the weight oi the separator distributedapproximatelyevenly on each side of the main carriage axle, so that themain carriage axle can carry it and relieve the fore carriage of themajor part of the weight of the apparatus.

The motor /ly is located on the main carriage a below the front end ofthe separator i and in rear or' the fore carriage (l and is rigidlysupported by the-frame work carried by the side beams g of the maincarriage 0.. Carried by the niain carriage a and forming an essentialpart or the motor I nechanism is a fan fw, inclosed by a fan casalegresing w and surrounding or partially surrounding the fan casing fc is awater cooler y connected with the water aclret fofthe motor bycirculating pipes z, so that the water may continuously liow from theWater jacket ol the motor to theywater cooling casing oi the fan andthen return tothe former. The fan te is preferably driven :from themotor by a drive belt a', passing around the drivepulley b on the motorshaft c and around a driven pulley al on the fan shaft. The revolutionof the fan creates an induced air `current which beats against the innerface of the Water cooling casing ot' the fan, which may be eitherseparate trom but in contact with, or may form part of, the casing oi'the Water cooler, and the air currents as they beat against it ab# sorbthe calories or heat units radiated from the water circulating throughthe water cooler and reduce the temperature of the water before itreturns to the water jacket'. ot' the motor. ly this means it ispossible to maintain a low temperature for the engine parts with theemployment of a small Volume oi water.

The fan w is positioned on the traction truck so that it can be employedvas a fan for the separator to drive the induced air currents with theabsorbed calories or heat units 9.)

through the separating mechanism to dry or assist in the drying 'of thegrain and straw passing through it.

The motive 'mechanism of the traction truck transmits by a 'suitabletransmission 100 gear i propelling motion to the traction wheelscontrolled by a suitable arrangement of friction clutches 3a and levers8b. This gear may be so arranged that it can be o erated independentlyof the 'separating 105Y mechanism or 'in unison therewith, or thepropelling mechanism can be stopped during the actuation of theseparating mechanism,

or theseparating mechanism can be stopped during the actuation of themechanism.

As shown in the drawings the fore car riage platformextends forwardlyfrom the. front end of the separator and has 'suioient 4 acconnnodationfor the motor i controlling 115 mechanism j, storage tanks la, toolchest o and accommodation for the driver of the apparatus and one ormore assistants Who are protected by a canopy p supported by thestandards g connected to the fore carriage 120 and to the front of theseparator and who .may be further protected' by side curtains connectedto the canopy. 1
